[0090] In order to illustrate the technical solutions described in the present application, the following will be described in detail in combination with specific drawings and embodiments.

[0091] Please refer to Figures 1 to 4 The embodiment of the present application provides a clothes treatment apparatus 200.

[0092] Based on the normal working state of the clothes treatment apparatus 200, for the purpose of description and understanding, "up", "down", "left", "right", "front", "back" are defined here, the side of the clothes treatment apparatus 200 facing the user is "front", the side away from the user is "back", the side facing the ground is "down", the side away from the ground is "up", the side corresponding to the left hand of the user is "left", and the side corresponding to the right hand of the user is "right".

[0093] As shown in Figures 1 to 4 The clothes treatment apparatus 200 includes an apparatus housing 1, and a drying module 100, a first driving member 5 and a drum 2 disposed in the apparatus housing 1. The first driving member 5 is connected with the drum 2 and used to drive the drum 2 to rotate.

[0094] As shown in Figure 2 , Figure 3 and Figure 4 The apparatus housing 1 can include a plurality of outer standing plates 15 connected with each other to surround the drying module 100. For example, the plurality of outer standing plates 15 of the apparatus housing 1 can include an upper side plate (or referred to as an upper cover plate), a front side plate (or referred to as a door plate), a left side plate, a right side plate and a back side plate, etc. In other embodiments, the plurality of outer standing plates 15 can have other numbers and be connected in other orientations.

[0095] Please refer to Figure 2 , Figure 3 and Figure 4 , and Figure 8As shown, the drum 2 is provided with an air inlet 21 and an air outlet 23, and a space between the air inlet 21 and the air outlet 23 serves as a laundry treatment space 22.

[0096] Referring to Figure 2 and Figure 3 As shown, the equipment housing 1 can further include a first support 16 disposed between the front side plate and the drum 2, and a second support (not shown) disposed between the rear side plate and the drum 2, and the drum 2 is rotatably mounted at both axial ends thereof between the first support 16 and the second support. In some embodiments, the second support can be integrally provided with the rear side plate.

[0097] In one embodiment, the air inlet 21 of the drum 2 can be disposed towards the front, i.e., towards the first support 16.

[0098] As shown in Figure 5 and Figure 6 The drying module 100 can include a base assembly 11 located below the drum 2, and a plurality of outer side plates 15 connected to the periphery of the base assembly 11 to define the drum 2 thereinside.

[0099] Referring to Figure 5 , Figure 6 and Figure 7 In one embodiment, the laundry treatment equipment 200 can further include a heat pump system 3 and a moisture absorption and removal system 4. The heat pump system 3 is configured to provide at least one cold source and at least one heat source, and to perform primary condensation and dehumidification and heating on air flowing out of the drum 2. The moisture absorption and removal system 4 is configured to perform primary moisture absorption and removal (secondary dehumidification) on air flowing out of the drum 2.

[0100] As shown in Figure 6 The heat pump system 3 includes, in sequence along a flow direction of a refrigerant, a compressor 31, a second heat exchanger 34, a throttling device 36, and a first heat exchanger 32.

[0101] The refrigerant can include hydrofluorocarbons (HFCs), chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), or natural refrigerants (e.g., ammonia, carbon dioxide, hydrocarbons, etc.). The second heat exchanger 34 serves as a heat source for heating air so that high-temperature air enters the drum 2, and the first heat exchanger 32 serves as a cold source for cooling and condensing air flowing out of the drum 2.

[0102] In one embodiment, as shown in Figure 6 and Figure 7As shown, a main drying air duct 110 is defined in the base assembly 11, and a receiving cavity 112 is also defined in the base assembly 11 and is isolated from the main drying air duct 110. The air inlet end of the main drying air duct 110 is in communication with the air outlet 23 of the drum 2, and the air outlet end of the main drying air duct 110 is in communication with the air inlet 21 of the drum 2. Please refer to Figure 6 and Figure 7 As shown, in the heat pump system 3, the first heat exchanger 32 and the second heat exchanger 34 are arranged along the air flow direction in the main drying air duct 110, and the compressor 31 and the throttling device 36 are arranged in the receiving cavity 112 of the base assembly 11.

[0103] In addition, please refer to Figure 5 As shown, the first driving member 5 and other components not involved in the air circulation are also arranged in the receiving cavity 112.

[0104] After passing through the first heat exchanger 32, the temperature of the air is reduced, the absolute humidity is reduced, and the relative humidity is increased. After passing through the second heat exchanger 34, the temperature of the air is increased, and the relative humidity is reduced.

[0105] In one embodiment, the first heat exchanger 32 comprises a first evaporator, and the second heat exchanger 34 comprises a condenser.

[0106] Absolute humidity: refers to the mass of water vapor contained in a unit volume of air, which directly reflects the actual content of water vapor in the air.

[0107] Relative humidity: refers to the percentage of the actual content of water vapor (absolute humidity) in the air to the saturated water vapor content at the same temperature, which is a relative concept and is used to describe the degree of saturation of water vapor in the air.

[0108] When the absolute humidity remains unchanged, the decrease in temperature will increase the relative humidity, and even possibly reach the saturated state of water vapor to produce condensation, i.e., produce condensate. When the absolute humidity remains unchanged, the increase in temperature will reduce the relative humidity and increase the unsaturated degree of water vapor in the air.

[0109] Therefore, after passing through the second heat exchanger 34, the air becomes high-temperature and low-humidity (low absolute humidity and low relative humidity), and after re-entering the drum 2, it can effectively remove the moisture in the clothes.

[0110] The moisture absorption and removal system 4 is used for absorbing and removing moisture (secondary dehumidification) from the air flowing out of the drum 2. At least a part of the moisture absorption and removal system 4 is arranged in the main drying air duct 110 and located between the first heat exchanger 32 and the second heat exchanger 34, and is used for absorbing and removing moisture from the low-temperature air after the first heat exchanger 32 to further reduce the absolute humidity and the relative humidity of the air.

[0111] Please refer to Figure 16As shown, in some embodiments, the moisture absorption and removal system 4 at least comprises a moisture absorption and removal element 42, a moisture absorption and removal shell 41, and a regeneration assembly 44, the moisture absorption and removal element 42 is arranged in the moisture absorption and removal shell 41 to play a moisture absorption and removal function.

[0112] Please refer to Figure 22 As shown, the space in the moisture absorption and removal shell 41 is divided into a moisture absorption zone 4102 and a desorption zone 4101. Please refer to Figure 16 As shown, the moisture absorption and removal element 42 comprises a moisture absorption part 4201 located in the moisture absorption zone 4102 and a desorption part 4202 located in the desorption zone 4101. The regeneration assembly 44 is in communication with the desorption zone 4101 to provide high-temperature air to the desorption zone 4101, thereby providing desorption energy (heat) for the moisture in the desorption part 4202.

[0113] In some embodiments, the shape of the moisture absorption and removal shell 41 can be designed according to the actual working condition requirements, as long as it at least comprises two functional zones of the moisture absorption zone 4102 and the desorption zone 4101, and the shape of each functional zone can also be designed according to actual needs, which can be square, triangular, circular, or sector, as long as the moisture absorption zone 4102 and the desorption zone 4101 are isolated from each other. In some embodiments, the sector-shaped moisture absorption zone 4102 and desorption zone 4101 can more effectively and reasonably utilize the space.

[0114] In some embodiments, the moisture absorption and removal element 42 is arranged in the moisture absorption and removal shell 41, as long as it can play a moisture absorption and removal function. The shape of the moisture absorption and removal element 42 is not limited, which can be a polygon such as a triangle or a square, or a wheel disc shape, such as Figure 16 and Figure 18 As shown, the design of the wheel disc-shaped moisture absorption and removal element 42 can make the moisture absorption and removal element 42 move between the moisture absorption zone 4102 and the desorption zone 4101. The part of the moisture absorption and removal element 42 (i.e. the moisture absorption part 4201) moving to the moisture absorption zone 4102 absorbs the moisture in the air, and then the part of the moisture absorption and removal element 42 (i.e. the desorption part 4202) moving to the desorption zone 4101 desorbs the moisture. The part of the moisture absorption and removal element 42 (i.e. the desorption part 4202) after desorption moves to the moisture absorption zone 4102 to absorb moisture, which is cyclically repeated to remove the moisture in the air, thereby achieving the effect of moisture absorption and removal.

[0115] In some embodiments, the moisture absorbing and removing member 42 is a desiccant wheel member, and the desiccant wheel in the desiccant wheel member can be a honeycomb or corrugated wheel loaded with a desiccant, which can adsorb and desorb the absorbed water vapor to realize repeated desorption and regeneration. In some embodiments, the desiccant wheel includes inorganic / organic fiber carriers such as ceramic, glass fiber, MOFs (Metal-Organic Frameworks), COFs (Covalent-Organic Frameworks), cordierite, etc., and the fiber carriers are coated with a desiccant such as a molecular sieve, which is uniformly distributed between the fiber carriers and on the surface of the fiber carriers to realize adsorption of the moisture in the air flow. The desiccant can be, for example, a zeolite, a modified / synthetic zeolite, a molecular sieve (including but not limited to single-crystal molecular sieves or mixed-crystal molecular sieves such as A-type molecular sieves, X / Y-type molecular sieves, ZSM molecular sieves, Beta molecular sieves, etc.), a polymer desiccant, an alkali metal aluminosilicate (13X molecular sieve), lithium chloride, silica gel, modified silica gel, activated alumina, or other materials with moisture absorption properties.

[0116] In an optional embodiment, the moisture absorbing and removing member 42 is a molecular sieve desiccant wheel.

[0117] In an embodiment, the regeneration assembly 44 is a heating member for heating the air in the desorption area 4101. In an embodiment, the regeneration assembly 44 includes an electric heating member.

[0118] Then, please refer to Figure 6 , Figure 7 and Figure 8 , in an embodiment, the heat pump system 3 further includes a third heat exchanger 33, which is connected in series between the throttling device 36 and the first heat exchanger 32 or between the first heat exchanger 32 and the compressor 31. The third heat exchanger 33 serves as another cold source for cooling and dehumidifying the high-temperature air after the desorption area 4202 to reduce the absolute humidity of the air after the desorption area 4202.

[0119] By using the third heat exchanger 33 as the cold source of the moisture absorbing and removing system 4, the internal heat circulation during the regeneration process of the moisture absorbing and removing system 4 can be further realized, and the high-temperature air can be prevented from being discharged to the outside of the equipment housing 1. The applicability of the laundry treatment apparatus 200 is more extensive.

[0120] In an embodiment, the third heat exchanger 33 includes a second evaporator.

[0121] In an embodiment, based on the design of the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11, the third heat exchanger 33 is connected in series between the throttling device 36 and the first heat exchanger 32, please refer to Figure 6 andFigure 7 That is, the compressor 31, the second heat exchanger 34, the throttling device 36, the third heat exchanger 33 and the first heat exchanger 32 are connected in sequence along the direction of refrigerant outflow.

[0122] In other alternative embodiments, based on the design of the base assembly 11, or other design requirements, the compressor 31, the second heat exchanger 34, the throttling device 36, the first heat exchanger 32 and the third heat exchanger 33 can be connected in sequence along the direction of refrigerant outflow. In other alternative embodiments, based on the design of the base assembly 11, or other design requirements, the third heat exchanger 33 can be connected in parallel with the first heat exchanger 32 downstream of the throttling device 36; or the throttling device 36 includes two throttling devices connected in parallel, one of which is connected in series with the first heat exchanger 32, and the other of which is connected in series with the third heat exchanger 33, and the first heat exchanger 32 and the third heat exchanger 33 are connected in parallel.

[0123] Please refer to Figure 6 As shown in the figure, the base assembly 11 is also provided with a regeneration air duct, which is at least composed of the desorption area 4101 in the moisture absorption and removal shell 41 and the first air duct part 1111 connected in communication, and is used to accommodate the desorption part 4202 of the moisture absorption and removal part 42 and the third heat exchanger 33. The regeneration air duct and the main drying air duct 110 are functionally independent and structurally isolated.

[0124] Next, the base assembly 11 and the arrangement of the heat pump system 3 on the base assembly 11 will be described in detail.

[0125] Please refer to Figure 5 、 Figure 6 、 Figure 11 and Figure 12 As shown in the figure, the base assembly 11 includes a base 12 and an upper cover 13, as shown in Figure 5 and Figure 6 The base 12 includes a bottom plate 120 and a first side plate 121 provided on the upper surface of the bottom plate 120, and the upper cover 13 is connected with the end surface of the first side plate 121 away from the bottom plate 120, that is, the upper end surface of the first side plate 121, to define the main drying air duct 110 described above.

[0126] In one alternative embodiment, as shown in Figure 7 and Figure 16As shown, at least a part of the moisture absorption and removal shell 41 and the moisture absorption and removal member 42 are arranged in the main drying air duct 110, and the rotation center axis of the moisture absorption and removal member 42 is parallel to the air direction in the main drying air duct 110. It can be understood that, here, the rotation center axis of the moisture absorption and removal member 42 is not parallel to the air direction at any position in the main drying air duct 110, but is parallel to the air direction in the part of the main drying air duct 110 in which the moisture absorption and removal member 42 is arranged. That is, the air passing through the moisture absorption and removal member 42 flows straight in the main drying air duct 110.

[0127] The purpose of such arrangement is to make the air flow straight in the part of the main drying air duct 110 in which the moisture absorption and removal member 42 is arranged, thereby reducing the air reversing and vortex generation, and improving the air flow efficiency of the drying module 100 and reducing the air resistance. In addition, no complicated isolation and sealing structure is required between the main drying air duct 110 and the moisture absorption and removal system 4, and the clothes treatment apparatus 200 has the advantages of fast drying speed and low energy consumption.

[0128] As shown in Figure 5 and Figure 6 In one embodiment, the base 12 further includes a second side plate 122 arranged on the upper surface of the bottom plate 120 and located beside the first side plate 121. The upper cover 13 is further connected with the upper end surface of the second side plate 122 to define the first air duct part 1111 of the regeneration air duct.

[0129] In one embodiment, the moisture absorption and removal shell 41 arranged in the main drying air duct 110 is provided with a second air duct part. The first air duct part 1111 and the second air duct part are in communication and constitute the regeneration air duct. The first air duct part 1111 is used to arrange the second heat exchanger 34.

[0130] It can be understood that, as far as the base assembly 11 is concerned, no obvious partition structure is required to be arranged in the main drying air duct 110 to divide the part for accommodating the moisture absorption and removal shell 41, but the moisture absorption and removal shell 41 arranged in the main drying air duct 110 itself internally defines another part of the regeneration air duct, i.e., the desorption area 4101.

[0131] The first heat exchanger 32 and the second heat exchanger 34 are arranged in the main drying air duct 110, i.e., at the upper surface of the bottom plate 120, and the first heat exchanger 32 generates condensed water around it. Therefore, in one embodiment, as shown in Figure 11 and Figure 12 The bottom plate 120 is provided with a water running channel 113 located in the main drying air duct 110, or the condensed water drops on the upper surface of the bottom plate 120, and the part of the main drying air duct 110 located below can serve as the water running channel 113.

[0132] As shown in Figure 5 , Figure 6 andFigure 11 As shown, the bottom plate 120 includes a water collecting box 123 outside the first side plate 121, and a first water outlet 1210 is arranged on the first side plate 121 and / or the bottom plate 120, and the first water outlet 1210 is communicated with the water channel 113 and the water collecting box 123. Also, as shown, Figure 11 As shown, the bottom surface of the water channel 113 (i.e. the upper surface of the portion of the bottom plate 120 located inside the main drying air duct 110) gradually decreases in the direction towards the first water outlet 1210. In this way, the condensed water can automatically flow to the first water outlet 1210 and enter the water collecting box 123.

[0133] The water collecting box 123 can be arranged as a drawer type, a screw type or other detachable water collecting structure, or can be drained into the sewer through a water pipe.

[0134] As shown, Figure 12 The third heat exchanger 33 inside the first air duct portion 1111 can also generate condensed water, and the condensed water drops onto the upper surface of the bottom plate 120 located inside the first air duct portion 1111, or in other words, the portion of the first air duct portion 1111 located below also serves as the water channel 113. A second water outlet 1220 is arranged on the second side plate 122 and / or the bottom plate 120. In the first air duct portion 1111, the upper surface of the bottom plate 120 gradually decreases in the direction towards the second water outlet 1220, and the second water outlet 1220 is communicated with the water collecting box 123. In an optional embodiment, according to the positional relationship between the first air duct portion 1111 and the main drying air duct 110, the first water outlet 1210 can be communicated with the main drying air duct 110 and the first water outlet 1210 in sequence.

[0135] As shown in Figure 6 , Figure 11 and Figure 12 In an embodiment, the base assembly 11 further includes an isolation plate 14 arranged inside the main drying air duct 110, and the isolation plate 14 is spaced apart from the upper surface of the bottom plate 120 and forms the water channel 113. At least one water leakage hole 141 is arranged on the isolation plate 14 corresponding to the position of the first heat exchanger 32. In this way, the first heat exchanger 32 and the second heat exchanger 34 can be carried on the isolation plate 14, and the condensed water generated on the first heat exchanger 32 can enter the water channel 113 through the water leakage hole 141.

[0136] As shown, Figure 6 , Figure 11 and Figure 12As shown, in one embodiment, the upper surface of the bottom plate 120 is provided with a plurality of raised blocks 124, which are used to support the isolation plate 14 at a certain height, i.e., the isolation plate 14 is arranged at the end surface of the raised blocks 124 facing the upper cover 13. Among them, in order to be able to uniformly support the isolation plate 14 at multiple positions, the raised blocks 124 are designed in different shapes and positions. For example, referring to Figure 6 As shown, a part of the raised blocks 124 (first raised blocks 1241) are arranged on the inner circumferential wall of the first side plate 121, which are used to support the edge of the isolation plate 14, and another part of the raised blocks 124 (a plurality of second raised blocks 1242) are arranged in the water running channel 113 and the main drying air duct 110, which are used to support the middle part of the isolation plate 14 at multiple points.

[0137] As shown in Figure 11 and Figure 12 , in one embodiment, a part of the raised blocks 124 (third raised blocks 1243) are arranged to surround each other in the water running channel 113 and define a first mounting cavity 1240, which is arranged to accommodate a part of the moisture absorption and removal system 4, specifically, a part of the moisture absorption and removal shell 41. The isolation plate 14 is provided with a corresponding avoiding opening 143 corresponding to the first mounting cavity 1240, as shown in Figure 11 . In this way, the moisture absorption and removal system 4 can be partially located above the isolation plate 14 and partially located below the isolation plate 14, and is isolated from the water running channel 113. The purpose of this arrangement is that in the up-down direction, the moisture absorption and removal system 4 can be as close to the bottom plate 120 as possible, so as to lower the position of the moisture absorption and removal system 4, and thus lower the overall height of the clothes treatment equipment 200.

[0138] In an optional embodiment, the lower surface of the bottom plate 120 can be downwardly protruded corresponding to the first mounting cavity 1240, and the upper surface of the bottom plate 120 can be downwardly recessed corresponding to the first mounting cavity 1240, if allowed, as shown in Figure 6 and Figure 11 , so as to further lower the position of the moisture absorption and removal system 4.

[0139] Please refer to Figure 6 , the upper surface of the isolation plate 14 corresponding to the first heat exchanger 32 is designed as a downwardly recessed surface, and at least part of the water leakage hole 141 is arranged on the recessed surface. The purpose of this design is to better guide the water dripping from the first heat exchanger 32 to the water leakage hole 141, and then to the water running channel 113 below the isolation plate 14.

[0140] In addition, condensate water will also be generated around the first heat exchanger 32. Therefore, in one embodiment, please refer to Figure 6 and Figure 12 .As shown, the upper surface of the isolation plate 14 is provided with a water baffle 142, which is located on the side of the first heat exchanger 32 close to the moisture absorption and dehumidification system 4 and is spaced apart from the first heat exchanger 32. The water leakage hole 141 and the avoidance opening 143 are respectively located on the opposite sides of the water baffle 142. The purpose of such arrangement is that since the wind direction is from the first heat exchanger 32 to the moisture absorption and dehumidification system 4, there will be obvious condensate water in the part of the space downstream of the first heat exchanger 32, and the water baffle 142 can block part of the condensate water from the avoidance opening 143 and prevent the condensate water from entering the avoidance opening 143 and the first mounting cavity 1240. According to the height relationship between the concave surface and the water baffle 142, one or more water leakage holes 141 can be arranged on the side of the water baffle 142 close to the first heat exchanger 32, such as Figure 13 As shown.

[0141] As shown in Figure 6 and Figure 6 In one embodiment, the isolation plate 14 is provided with a downwardly extending flange 144 around the periphery of the avoidance opening 143. The flange 144 can be in a closed enclosure style. Therefore, the flange 144 is located in the first mounting cavity 1240. The purpose of such arrangement is that the flange 144 can play a guiding role for the moisture absorption and dehumidification system 4 when the moisture absorption and dehumidification system 4 is assembled. In addition, through the interference fit between the flange 144 and the first pad, the condensate water in the water channel 113 can be further prevented from entering the first mounting cavity 1240.

[0142] In one embodiment, the isolation plate 14 can be fixedly connected with at least one pad 124 by fasteners, for example, fixedly connected with the third pad 1243 by fasteners. The fasteners can be bolts, screws, etc., or other structures that can be fixed.

[0143] In one embodiment, the lower surface of the isolation plate 14 is connected with at least one pad 124 through a limiting fit structure. For example, the upper surface of at least the first pad 1241 is provided with a limiting structure (not shown), and the lower surface of the isolation plate 14 is provided with a matching structure (not shown) corresponding to the limiting structure. The limiting structure can be a groove or a protrusion, and the matching structure can be a protrusion or a groove. Through the concave-convex fit between the upper surface of the first pad 1241 and the lower surface of the isolation plate 14, the installation stability of the isolation plate 14 on the pad 124 can be further ensured.

[0144] In other embodiments, other pads 124 and the isolation plate 14 can also be connected through fasteners and / or limiting fit structures. For example, the third pad 1243 is connected with the isolation plate 14 through fasteners, and for example, the second pad 1242 is connected with the isolation plate 14 through a limiting fit structure.

[0145] Please refer to Figure 7 As shown in

[0146] As shown in Figure 4 The second side plate 122 is connected with a part of the first side plate 121, or in other words, a part of the first side plate 121 is used to define the first air duct part 1111 together with the second side plate 122. Figure 8 Figure 9 As shown in

[0147] Please refer to Figure 6 The first driving member 5 is used to drive the rotation of the drum 2. The first driving member 5 can specifically include a first motor, a synchronous wheel and a first synchronous belt (not shown). The first motor drives the rotation of the synchronous wheel, the synchronous wheel drives the rotation of the synchronous belt, and the synchronous belt is sleeved on the outer circumferential surface of the drum 2 to drive the synchronous rotation of the drum 2.

[0148] In an embodiment, the first driving member 5 can include a second synchronous belt, a connecting arm and a tensioning member (all not shown). The connecting arm is movably arranged on the first motor and connected with the synchronous wheel. The second synchronous belt is connected between the synchronous wheel and the driving shaft of the first motor. One end of the tensioning member is connected with the synchronous wheel, and the other end is connected to the bottom plate 120 to tension at least the second synchronous belt. The tensioning member can be a spring, a tensioning rope or the like. ​

[0149] As shown in Figure 7 , in one embodiment, the bottom plate 120 is provided with a mounting portion 127, and the bottom plate 120 is provided with a chamfered arc surface 1270 on the protrusion inside the mounting portion 127. Generally, based on the positional relationship between the tensioning member and the synchronous wheel, the tensioning member is arranged to be inclined with respect to the vertical direction and the horizontal direction, and the chamfered arc surface 1270 is used to avoid the tensioning member, so as to avoid the interference caused by the elastic expansion of the right-angle surface to the tensioning member.

[0150] The rear side of the base 12 is used to be connected with the rear side plate. As shown in Figure 11 , in one embodiment, the edge of the bottom plate 120 is provided with a plurality of guide blocks 126, the guide blocks 126 are located at the periphery of the first side plate 121, and the side of the guide block 126 facing the first side plate 121 is provided with a guide surface 1260, which is inclined to the first side plate 121 in the direction from the upper cover 13 to the bottom plate 120. In this way, when the rear side plate is installed, the rear side plate is aligned with the guide blocks 126 and moved from top to bottom, the rear side plate slides along the guide surface 1260 and enters the front side of the guide block 126, thereby realizing the rapid positioning and pre-fixing connection between the rear side plate and the base 12.

[0151] Please refer to Figure 11 , Figure 2 and Figure 3 , in one embodiment, the base 12 further includes a third side plate 125 provided on the bottom plate 120 and located outside the first side plate 121 and the second side plate 122, and the third side plate 125 defines a front air duct 1250; as shown in Figure 2 , the third side plate 125 is provided with a fourth communication port 1251 connected with the main drying air duct 110, and the end surface of the third side plate 125 away from the bottom plate 120 defines a fifth communication port 1252, and the second communication port 1212 is used to communicate with the air outlet 23 of the drum 2.

[0152] In one embodiment, please refer to Figure 3 and Figure 2 , the first support 16 is provided with a third opening 161 corresponding to the air inlet 21 of the drum 2, and the third opening 161 is in communication with the air inlet 21 in the axial direction of the drum 2 and is aligned. In the process of rotating the drum 2, the air inlet 21 always communicates with the third opening 161. The third opening 161 also communicates with the front air duct 1250, so that the clothes processing space 22 of the drum 2 is communicated to the front air duct 1250.

[0153] Please refer to Figure 3 and Figure 6As shown, a filter duct 160 is formed on the inner peripheral wall of the third opening 161 on the first support member 16, and the filter duct 160 connects the front air duct 1250 and the third opening 161. This achieves communication between the third opening 161 and the front air duct 1250. Optionally, a filter device (not shown) may be provided in the filter duct 160 to filter lint and other debris carried by the air flowing out of the roller 2. Optionally, a filter device may also be provided in the front air duct 1250. The filter device includes, but is not limited to, filter boxes, filter plates, etc.

[0154] Reference Figure 12 and Figure 16 As shown, the first support member 16 is located above the third side plate 125. The filter duct 160 and the front duct 1250 are generally aligned and connected in the vertical direction.

[0155] Please see Figure 17 and Figure 6 As shown, in one embodiment, the upper cover 13 is provided with a first cable routing hole 132. The first cable routing hole 132 is used for power lines, signal lines, etc. to pass through. In some embodiments, the regeneration assembly 44 includes a heating element 441; please refer to the relevant documentation. Figure 12 and Figure 4 As shown, heating element 441 is specifically an electric heating element. In this case, the power supply line is used to provide power to the electric heating element.

[0156] like Figure 4 and Figure 6 As shown, the edge of the upper cover 13 is provided with a plurality of spaced wire fixing blocks 133. The wire fixing blocks 133 are used to fix power lines, signal lines, etc. that pass through the first wire hole 132. The form of the wire fixing blocks 133 is not limited.

[0157] Please see Figure 12 As shown, in one embodiment, the clothing processing device 200 further includes a main circulation fan 6, which is at least partially disposed in the main drying duct 110. The first driving member 5 is connected to the main circulation fan 6 to drive the main circulation fan 6 to rotate. The main circulation fan 6 is used to drive the airflow in the main drying duct 110.

[0158] In one embodiment, such as Figure 6 As shown, the main circulating fan 6 is located downstream of the second heat exchanger 34 and is used to transport the air from the main drying air duct 110 to the air inlet 21 of the drum 2.

[0159] In one embodiment, the first driving member 5 is a double driving member, such as a double rotor motor, having a first driving shaft and a second driving shaft (not shown), the second driving shaft being used to drive the drum 2, and the first driving shaft being used to connect with the main circulating fan 6. In this way, one first driving member 5 can be used to provide the rotation of the drum 2 and the main circulating fan 6, thereby saving the structural cost and reducing the volume occupation.

[0160] Please continue to refer to Figure 7 and Figure 10 As shown, the main circulating fan 6 is arranged between the upper cover 13 and the first side plate 121, and the upper cover 13 and / or the first side plate 121 is provided with a mounting position 135 for mounting the main circulating fan 6. For example, the mounting position 135 can be a mounting hole defined by the upper cover 13 and / or the first side plate 121. In order to adapt to the shape of the main circulating fan 6 and as low as possible the height of the base assembly 11 at least corresponding to the position of the main circulating fan 6, in one embodiment, the upper surface of the upper cover 13 corresponding to the main circulating fan 6 is provided with one or more reinforcing ribs 134, so as to as low as possible thin design of the upper cover 13 while ensuring the strength of the upper cover 13.

[0161] In one embodiment, any one of the base 12, the isolation plate 14 and the upper cover 13 can be a plastic member, for example, an integral structure formed by injection molding. In addition, the plastic base 12, the isolation plate 14 and the upper cover 13 also have a lower thermal conductivity, and the heat exchange between them and the air in the main drying air duct 110 and the regeneration air duct is lower.

[0162] Next, please refer to Figure 10 , Figure 6 and Figure 8 As shown, in the heat pump system 3, the compressor 31, the second heat exchanger 34, the throttling device, the third heat exchanger 33 and the first heat exchanger 32 are sequentially communicated through the refrigerant pipe 35.

[0163] During the operation of the compressor 31, the suction and discharge of the refrigerant are constantly occurring, and therefore the compressor 31 will generate vibration. Generally, the vibration is mostly multi-directional vibration in the horizontal plane. In order to reduce the pulling and extrusion of the refrigerant pipe 35 during the vibration of the compressor 31, and avoid the refrigerant pipe 35 from being broken, especially the part of the refrigerant pipe 35 close to the compressor 31, such as the refrigerant pipe 35 close to the compressor 31. Figure 10As shown, in one embodiment, the refrigerant pipe 35 comprises a plurality of pipe segments 351, adjacent pipe segments 351 are connected in a relative bending manner in a horizontal direction and / or a vertical direction. For example, when the compressor 31 vibrates along the left-right direction, and the first pipe segment 351 connected with the compressor 31 also extends along the left-right direction, the first pipe segment 351 will generate a moving amount along the left-right direction, and the second pipe segment 351 will generate a deflection or bending towards the left-right direction. For the pipe segments 351 connected in sequence and elongated (length greater than outer diameter), the deflection or bending will obviously reduce the risk of breakage compared to the pulling and extrusion along the length direction. When the plurality of pipe segments 351 are connected in sequence in a bending manner, the pulling and extrusion of the refrigerant pipe 35 caused by the vibration of the compressor 31 will be obviously improved.

[0164] The adjacent pipe segments 351 are connected in a relative bending manner in a horizontal direction, which means that the projections of the adjacent pipe segments 351 on a horizontal plane or on the bottom plate 120 are connected in a bending manner; the adjacent pipe segments 351 are connected in a relative bending manner in a vertical direction, which means that the projections of the adjacent pipe segments 351 in a vertical plane are connected in a bending manner.

[0165] In one embodiment, the refrigerant pipe 35 is a copper pipe. The copper pipe has good ductility, which is convenient for manufacturing the plurality of pipe segments 351 connected in a relative bending manner. Further optionally, the adjacent pipe segments 351 are connected in a smooth transition manner, so as to reduce the resistance of the refrigerant flowing between the pipe segments 351, and facilitate the assembly operation of the clothes treatment apparatus 200, etc.

[0166] As shown in Figure 15 and Figure 16 In one embodiment, the shell of the compressor 31 is provided with a plurality of first fixing ears 311, each first fixing ear 311 is provided with a fixing hole 3110, the first fastener 37 is arranged in the fixing hole 3110 and connected with the bottom plate 120, and the outer diameter of the first fastener 37 is smaller than the inner diameter of the fixing hole 3110. In this way, an annular gap is formed around the first fastener 37. The purpose of this arrangement is to adapt to the vibration of the compressor 31 as mentioned above. If the first fixing ear 311 is fixedly connected with the first fastener 37 without a gap, in the process of continuous vibration of the compressor 31, the first fixing ear 311 of the compressor 31 may be damaged, and even the shell of the compressor 31 may be damaged, and the vibration of the bottom plate 120 and the entire base 12 and base assembly 11 may be caused. In the embodiment of the present application, the vibration of the compressor 31 is transmitted to the refrigerant pipe 35, and is buffered and consumed by the pipe segments 351 connected in a bending manner, which reduces the damage to the compressor 31 itself, and also reduces the vibration of the entire clothes treatment apparatus 200.

[0167] In one optional embodiment, please refer to Figure 17As shown, in the heat pump system 3, a plurality of sequentially connected pipe sections 351 define an avoiding space 350 for accommodating the first driving member 5. The purpose of such arrangement is that the refrigerant pipe 35 and the first driving member 5 are both arranged in the accommodating cavity 112 of the bottom plate 120, and the refrigerant pipe 35 needs to avoid the first driving member 5, and optionally, at least a portion of the refrigerant pipe 35 is located below the first driving member 5 so as not to affect the connection between the first driving member 5 and the drum 2. Therefore, the portion of the pipe section 351 located below the first driving member 5 and the portion of the pipe section 351 located around the first driving member 5 are arranged to adapt to the shape of the first driving member 5, thereby defining the above-mentioned avoiding space 350.

[0168] Next, the moisture absorption and removal system 4 of the embodiment of the present application is introduced.

[0169] Please refer to Figure 22 、 Figure 14 、 Figure 16 and Figure 22 , in one embodiment, in the moisture absorption and removal system 4, the moisture absorption and removal shell 41 is provided with a first opening 4110, as shown in Figure 14 、 Figure 16 and Figure 22 , the moisture absorption and removal shell 41 is further provided with a second opening 4120, the first opening 4110 and the second opening 4120 respectively expose a part of the surface of the moisture absorption and removal member 42, so that the first opening 4110 and the second opening 4120 are in communication through the moisture absorption part 4201 of the moisture absorption and removal member 42, and the air passes through the passageway formed by the first opening 4110, the moisture absorption part 4201 and the second opening 4120 in sequence, and the moisture in the air can be absorbed by the moisture absorption part 4201. The part of the moisture absorption and removal shell 41 corresponding to the part between the first opening 4110 and the second opening 4120 is the said moisture absorption area 4102.

[0170] In one optional embodiment, please refer to Figure 15 、 Figure 16 and Figure 17 , the first opening 4110 is formed on the first axial end surface of the moisture absorption and removal shell 41, and the first opening 4110 exposes a part of the first axial end surface of the moisture absorption and removal member 42. In this way, the first opening 4110 can be made in a simple form and has a larger area, which facilitates to increase the air passing area of the moisture absorption part 4201 and improve the absorption efficiency of the moisture in the moisture absorption part 4201.

[0171] In one optional embodiment, please refer to Figure 22 、 Figure 16 、 Figure 21 and Figure 22As shown, the second opening 4120 is formed on the second axial end surface of the moisture absorbing and releasing shell 41, and exposes a portion of the second axial end surface of the moisture absorbing and releasing member 42. Similarly, this allows the second opening 4120 to be made in a simple form and have a larger area, facilitating an increase in the air passing area of the moisture absorbing portion 4201 and an improvement in the moisture adsorption efficiency in the moisture absorbing portion 4201.

[0172] In an optional embodiment, as shown in Figure 16 , Figure 17 and Figure 22 , the first opening 4110 is formed on the first axial end surface of the moisture absorbing and releasing shell 41, and the second opening 4120 is formed on the second axial end surface of the moisture absorbing and releasing shell 41. Overall, the moisture absorbing and releasing shell 41 and the moisture absorbing and releasing member 42 have a larger air passing area, which is conducive to improving the moisture adsorption efficiency, reducing the consumption of air kinetic energy, reducing energy consumption, and improving drying efficiency.

[0173] Further optionally, as shown in Figure 7 , Figure 7 and Figure 16 , the first opening 4110 and the second opening 4120 communicate with each other along the axial direction through the moisture absorbing portion 4201 of the moisture absorbing and releasing member 42. In this way, the first opening 4110 and the second opening 4120 are aligned and communicated along the axial direction of the moisture absorbing and releasing member 42. The air passes through the moisture absorbing and releasing member 42 along the axial direction, which has a larger air passing area and adsorption area, and has a smaller air resistance, which is conducive to improving the flow speed of the air in the moisture absorbing and releasing system 4, thereby improving the moisture desorption efficiency and reducing energy consumption.

[0174] In an embodiment, the first axial end surface and the second axial end surface of the moisture absorbing and releasing member 42 are circular. The first opening 4110 and the second opening 4120 are both fan-shaped. Optionally, the area of the first opening 4110 and the second opening 4120 is more than 50% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further optionally, the area of the first opening 4110 and the second opening 4120 is more than 60% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further optionally, the area of the first opening 4110 and the second opening 4120 is more than 70% of the area of the axial end surface of the moisture absorbing and releasing member 42. Further optionally, the area of the first opening 4110 and the second opening 4120 is more than 80% of the area of the axial end surface of the moisture absorbing and releasing member 42. In this way, it is ensured that the first opening 4110 and the second opening 4120 both have sufficient area, and at the same time, the moisture absorbing and releasing member 42 allows a smaller diameter and volume to be designed, which is conducive to reducing the overall volume of the moisture absorbing and releasing system 4 and the overall volume of the clothes treatment apparatus 200.

[0175] Please refer to Figure 17As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the axial direction of the moisture absorption and removal member 42 in sequence. Figure 21 As shown, in one embodiment, the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged in the main drying air duct 110 along the axial direction of the moisture absorption and removal member 42 in sequence,

[0176] As shown in Figure 22 , Figure 16 , Figure 17 and Figure 22 , the moisture absorption and removal shell 41 includes a first shell 411 and a second shell 412, which are connected opposite to each other on both sides of the axial direction of the moisture absorption and removal member 42 to confine the moisture absorption and removal member 42. The first opening 4110 is arranged on the first shell 411, and the second opening 4120 is arranged on the second shell 412. The first shell 411 and the second shell 412 can be connected by fasteners such as bolts, screws, etc. In addition, as shown in Figure 22 and Figure 14 , in one optional embodiment, according to the shape of the first shell 411 and the second shell 412, at positions where it is inconvenient to arrange fasteners, a ring-shaped connecting member 414 can also be sleeved on the first shell 411 and the second shell 412 to achieve further fixed connection of the first shell 411 and the second shell 412.

[0177] As shown in Figure 16 , the area of the first shell 411 that avoids the first opening 4110 and the area of the second shell 412 that avoids the second opening 4120 are connected along the axial direction of the moisture absorption and removal member 42 to form a second air duct part, i.e., the desorption area 4101 of the moisture absorption and removal shell 41. In this way, the moisture absorption and removal shell 41 is arranged at least partially in the main drying air duct 110, and the second air duct part in the moisture absorption and removal shell 41 is connected in communication with the first air duct part 1111 outside the main drying air duct 110, thereby forming a regeneration air duct.

[0178] Please refer to Figure 22 As shown in

[0179] The first opening 4110 is used for air intake, and the second opening 4120 is used for air exhaust. In this embodiment, the air flow direction in the desorption part 4202 is opposite to the air flow direction in the moisture absorption part 4201, which is conducive to improving the desorption efficiency.

[0180] In other alternative embodiments, the air exhaust air duct part 4115 can also be formed on the second shell 412, and the air intake air duct part 4125 is formed on the first shell 411, so that the air flow direction in the desorption part 4202 is the same as the air flow direction in the moisture absorption part 4201; or the first opening 4110 is used for air exhaust, and the second opening 4120 is used for air intake, so that the air flow direction in the desorption part 4202 is the same as the air flow direction in the moisture absorption part 4201.

[0181] Please refer to Figure 22 , Figure 15 and Figure 16 As shown in one embodiment, the first shell 411 is provided with a first outer air guide surface 4114, and the first outer air guide surface 4114 is arranged to be inclined to the axial direction of the moisture absorption and dehumidification part 42, specifically, gradually inclined to the desorption part 4202 in the direction toward the central axis of the moisture absorption and dehumidification part 42.

[0182] The first outer air guide surface 4114 is used to guide the air in the main drying air duct 110, so that the air is gradually concentrated into the first opening 4110 on the moisture absorption and dehumidification shell 41, avoiding vortex when the air reaches the surface of the first shell 411. Among them, Figure 16 The solid triangle arrow in indicates the direction of the wind. Further, this can ensure the air flow speed in the main drying air duct 110, ensure the adsorption efficiency of the moisture in the moisture absorption part 4201, reduce the energy consumption of the clothes treatment equipment 200, and improve the drying efficiency of the clothes treatment equipment 200.

[0183] In one alternative embodiment, please refer to Figure 17 and Figure 22 The width of the first outer air guide surface 4114 gradually decreases in the direction toward the central axis of the moisture absorption and dehumidification part 42. That is to say, from the axial direction of the moisture absorption and dehumidification part 42, the first outer air guide surface 4114 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0184] Please continue reading. Figure 14 , Figure 16 and Figure 22 As shown, in one embodiment, the second housing 412 is further provided with a second external air guide surface 4124. The second external air guide surface 4124 is axially inclined to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The purpose of this arrangement is to guide the air in the main drying air duct 110 so that after the air flows out from the second opening 4120, it flows evenly to the second heat exchanger 34, avoiding the generation of eddies between the second housing 412 and the second heat exchanger 34.

[0185] This ensures the airflow speed within the main drying duct 110, guarantees the moisture adsorption efficiency in the moisture absorption section 4201, reduces the energy consumption of the garment processing equipment 200, and improves the drying efficiency of the garment processing equipment 200.

[0186] In one alternative embodiment, please refer to Figure 16 As shown, the width of the second outer air guide surface 4124 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation component 42. That is to say, viewed from the axial direction of the moisture absorption and desiccation component 42, the second outer air guide surface 4124 is fan-shaped, which corresponds to the fan-shaped shape of the second opening 4120.

[0187] Please continue reading. Figure 17 and Figure 22 As shown, in one embodiment, a first inner air guide surface 4113 is provided on the inner wall of the first housing 411. The first inner air guide surface 4113 is inclined axially to the moisture absorption and desiccation component 42, specifically, it gradually inclines towards the desorption portion 4202 in the direction towards the central axis of the moisture absorption and desiccation component 42. The first inner air guide surface 4113 is used to guide the air flowing out of the desorption portion 4202 to change direction, avoiding abrupt reversal of air flow from the desorption portion 4202 to the third heat exchanger 33, which would cause eddies and energy loss. Optionally, the first outer air guide surface 4114 is generally parallel to the first inner air guide surface 4113.

[0188] Furthermore, by setting the first inner air guide surface 4113, the airflow speed inside the moisture absorption and dehumidification system 4 is guaranteed, the desorption efficiency of moisture in the desorption section 4202 is guaranteed, the energy consumption of the clothing processing equipment 200 is reduced, and the drying efficiency of the clothing processing equipment 200 is improved.

[0189] In one alternative embodiment, the width of the first inner air guide surface 4113 gradually decreases in the direction toward the central axis of the moisture absorption and desiccation member 42. That is, viewed from the axial direction of the moisture absorption and desiccation member 42, the first inner air guide surface 4113 is fan-shaped, which corresponds to the fan-shaped shape of the first opening 4110.

[0190] Similarly, as shown in Figure 17 , Figure 22 and Figure 16 , in an embodiment, the inner wall of the second shell 412 is provided with a second inner air guide surface 4123, which is axially inclined to the moisture absorbing and removing member 42, specifically, gradually inclined to the desorption part 4202 in the direction towards the central axis of the moisture absorbing and removing member 42. The second inner air guide surface 4123 is used to change the direction of the air flowing out of the desorption part 4202, so as to avoid vortex flow and wind energy loss caused by sharp change of direction when the air flows from the third heat exchanger 33 to the desorption part 4202. Optionally, the second outer air guide surface 4124 is generally parallel to the second inner air guide surface 4123.

[0191] In an optional embodiment, as shown in Figure 17 , the width of the second inner air guide surface 4123 gradually decreases in the direction towards the central axis of the moisture absorbing and removing member 42. That is to say, as viewed from the axial direction of the moisture absorbing and removing member 42, the second inner air guide surface 4123 is in the shape of a sector, which corresponds to the sector shape of the second opening 4120.

[0192] In an embodiment, as shown in Figure 16 , the inner wall of the first shell 411 is provided with a first inner air guide surface 4113, and the inner wall of the second shell 412 is provided with a second inner air guide surface 4123. The first inner air guide surface 4113 and the second inner air guide surface 4123 are designed symmetrically about the radial plane of the moisture absorbing and removing member 42.

[0193] As shown in Figure 17 and Figure 17 , in an embodiment, the heating member 441 of the regeneration assembly 44 is arranged in the second shell 412, i.e. in the air inlet air duct part 4125, to heat the air entering the desorption part 4202. Specifically, the heating member 441 can be an electric heating pipe, an electric heating plate or other electric heating structural member, which is fixed on the inner wall surface of the second shell 412.

[0194] As shown in Figure 17 in combination, the heating member 441 is fixed on the inner wall surface of the second shell 412 and is arranged in a spaced manner with the second inner air guide surface 4123. The air in the air inlet air duct part 4125 is heated by the heating member 441 after being guided by the second inner air guide surface 4123. The purpose of this arrangement is that the heating member 441 is closer to the surface of the desorption part 4202 of the moisture absorbing and removing member 42, and the heat is more easily transferred to the moisture absorbing and removing member 42, so as to improve the energy utilization and the desorption efficiency of the desorption part 4202.

[0195] Specifically as Figure 17As shown, the heating element 441 is fixed on the inner wall surface of the second housing 412 by the second fastener 413. The specific form of the second fastener 413 is not limited as long as it can be adapted to the structure of the heating element 441. For example, for an electric heating tube, the fastener can be adapted to the surface of the tube body, and for an electric heating plate, the fastener can be adapted to the plate surface.

[0196] As shown in FIG. 4A, the second housing 412 is provided with a second inner air guide surface 4123. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. Figure 22 As shown, in one embodiment, the heating element 441 is fixed on the inner wall surface of the second housing 412 by the mounting plate 45. Since the heating element 441 is substantially aligned with the second inner air guide surface 4123 in the axial direction, in order to keep the heating element 441 substantially parallel to the axial surface of the moisture absorbing and removing element 42 to facilitate uniform heating of the heating element 441 to the surface of the desorption part 4202, a mounting plate 45 is provided to fix the heating element 441 and keep the orientation of the heating element 441. The mounting plate 45 can be in the form of a flat plate, maintaining a large contact area between the heating element 441 to ensure the stability of the installation of the heating element 441.

[0197] As shown, the mounting plate 45 is of a porous structure so as not to affect the flow of air from the second inner air guide surface 4123 to the heating element 441. Figure 14

[0198] As shown in FIG. 4A, the second housing 412 is provided with a second inner air guide surface 4123. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. Figures 14 to 17 Figure 6 As shown, in one embodiment, the second inner air guide surface 4123 is provided with a mounting table 4121 protruding towards the first housing 411, and the mounting plate 45 is arranged on the surface of the mounting table 4121 facing the first housing 411, and the second fastener 413 passes through the mounting plate 45 and is fastened on the mounting table 4121. In this way, the mounting plate 45 can be arranged spaced apart from the second inner air guide surface 4123, and the mounting position of the mounting plate 45 is also provided.

[0199] The mounting table 4121 is designed in a shape to reduce the space occupation in the air inlet duct part 4125 and reduce the obstruction to the air flow path. For example, the mounting table 4121 is generally in the form of a thin plate, and the thickness direction is generally perpendicular to the air flow direction in the air inlet duct part 4125, so the thickness is set to be small, which can reduce the obstruction to the air flow.

[0200] As shown in FIG. 4A, the second housing 412 is provided with a second inner air guide surface 4123. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. Figure 7 Figure 15 As shown, the second housing 412 is provided with one or more second wire passing holes 4126 corresponding to the heating element 441. The heating element 441 is connected to the external power supply by a power supply wire, and the second wire passing hole 4126 is used for the power supply wire to pass through.

[0201] As shown in FIG. 4A, the second housing 412 is provided with a second inner air guide surface 4123. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially parallel to the first inner air guide surface 4113. The second inner air guide surface 4123 is arranged to be substantially perpendicular to the first inner air guide surface 4113. Figure 16 ​​​As shown, the regeneration assembly 44 further comprises a regeneration fan 442, which is connected with the second shell 412, for example, the regeneration fan 442 can be arranged in the second shell 412 or connected with an end of the second shell 412 which is away from the second opening 4120. The regeneration fan 442 is used to provide flow power of air in the regeneration air duct.

[0202] As shown in Figure 20 and Figure 15 As shown, the regeneration fan 442 is arranged at the third communication opening 1221 of the second side plate 122 and forms communication with the first air duct part 1111 inside the second side plate 122. The second shell 412 communicates with the regeneration fan 442 via the second communication opening 1212.

[0203] As shown in Figure 16 , Figure 15 and Figure 20 As shown, the moisture absorption and removal system 4 further comprises a second driving member 43, which is fixed on the moisture absorption and removal shell 41 and is used to drive the moisture absorption and removal member 42 to rotate.

[0204] In an optional embodiment, the rotation central axis of the moisture absorption and removal member 42 and the rotation central axis of the drum 2 are arranged to be parallel to each other. The purpose of this arrangement is to facilitate the arrangement of structures in the equipment shell 1. Specifically, when the rotation central axis of the moisture absorption and removal member 42 and the rotation central axis of the drum 2 are parallel to each other, the part of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged is also parallel to the rotation central axis of the drum 2, that is, the part of the main drying air duct 110 in which the first heat exchanger 32, the moisture absorption and removal system 4 and the second heat exchanger 34 are arranged is arranged side by side with the drum 2 outside the drum 2, which realizes the maximum utilization of space in the equipment shell 1 and is conducive to ensuring the overall compact structure of the clothes treatment equipment 200.

[0205] In an embodiment, as shown in Figure 20 and Figure 20 The second driving member 43 is arranged on the first shell 411.

[0206] Alternatively, the second driving member 43 is arranged on a side surface of the first shell 411 which is away from the second shell 412. That is, the second driving member 43 is arranged between the moisture absorption and removal member 42 and the first heat exchanger 32. The purpose of this arrangement is that the air flowing from the first heat exchanger 32 to the second driving member 43 is low-temperature air, and the second driving member 43 is in a low-temperature and low-humidity environment, which is conducive to reducing the influence of water vapor and high temperature on the second driving member 43 and ensuring the service life of the second driving member 43.

[0207] Further, the second driving member 43 and the heating member 441 are located at the axial two sides of the moisture absorbing and removing member 42, which is beneficial to the axial two sides volume and space balance of the moisture absorbing and removing system 4, and beneficial to the flow symmetry of the air at the two sides of the moisture absorbing and removing system 4 in the main drying air duct 110, and reduces the pressure difference and air vortex caused by the space imbalance. In addition, the second driving member 43 and the heating member 441 are located at the axial two sides of the moisture absorbing and removing member 42, which is also beneficial to the weight balance of the two sides of the moisture absorbing and removing system 4.

[0208] As mentioned above, the first opening 4110 and the second opening 4120 are both fan-shaped, which can expose more surface of the moisture absorbing and removing member 42 for moisture adsorption. On this basis, in one embodiment, the second driving member 43 is staggered with the first opening 4110 in the axial direction of the moisture absorbing and removing member 42, please refer to Figure 20 As shown in the figure, the second driving member 43 is not aligned with the rotation center axis of the moisture absorbing and removing member 42, but offset from the first opening 4110 relative to the rotation center axis, that is, the second driving member 43 is offset from the first opening 4110 along the radial direction, and the second driving member 43 is arranged away from the first opening 4110 along the radial direction. The purpose of such arrangement is to reduce the obstruction of the second driving member 43 to the first opening 4110 in the axial direction of the moisture absorbing and removing member 42, and further reduce the obstruction to the air flow from the first heat exchanger 32 to the moisture absorbing and removing member 42, and improve the air speed and drying efficiency.

[0209] Please refer to Figure 16 As shown in the figure, in one embodiment, the second driving member 43 includes a second motor 432. The second motor 432 is arranged offset from the first opening 4110 relative to the rotation center axis of the moisture absorbing and removing member 42.

[0210] In an optional embodiment, the second motor 432 includes an eccentric motor, and the output shaft 4323 of the eccentric motor is connected coaxially with the moisture absorbing and removing member 42. In this way, the second driving member 43 is offset as a whole relative to the center axis of the moisture absorbing and removing member 42, but the output shaft 4323 of the second driving member 43 is aligned with the center axis of the moisture absorbing and removing member 42. There is no need to arrange a transmission assembly between the second driving member 43 and the moisture absorbing and removing member 42, which can simplify the structure of the moisture absorbing and removing system 4. At the same time, the purpose of such eccentric arrangement is to reduce the obstruction of the second driving member 43 to the first opening 4110, increase the air passing area of the moisture absorbing part 4201, and improve the drying efficiency.

[0211] In another embodiment, the output shaft 4323 of the second driving member 43 is connected to the moisture absorption and removal member 42 through a transmission assembly (not shown), and the output shaft 4323 of the second driving member 43 is further offset from the central axis of the moisture absorption and removal member 42 to the side away from the first opening 4110. In this way, the second driving member 43 can further reduce the obstruction of the first opening 4110, and the first opening 4110 can be as close as possible to the central axis of the moisture absorption and removal member 42, or even the second driving member 43 can not obstruct the first opening 4110 at all.

[0212] Referring to Figure 22 In one embodiment, the output shaft 4323 of the second driving member 43 has a plurality of flat surfaces 43230, which are distributed circumferentially symmetrically. When the output shaft 4323 is connected to and drives the moisture absorption and removal member 42 to rotate, the driving force is uniformly distributed on the plurality of flat surfaces 43230, which can increase the driving contact area between the output shaft 4323 and the moisture absorption and removal member 42, and can drive a larger moisture absorption and removal member 42 with a smaller diameter output shaft 4323, and the wear and fatigue damage of the output shaft 4323 and the moisture absorption and removal member 42 can be reduced.

[0213] In addition to the output shaft 4323, referring to Figure 20 The second motor 432 further includes a motor housing 4321, a rotating assembly (not shown) disposed in the motor housing 4321, and an electric control portion (not shown) disposed in the motor housing 4321 and connected to the rotating assembly. The output shaft 4323 passes through the motor housing 4321 and is connected to the rotating assembly, and the electric control portion is located on one side of the rotating assembly and is used to connect an external power source and the rotating assembly. The motor housing 4321 is fixedly connected to the side end surface of the first housing 411 away from the second housing 412.

[0214] In one embodiment, referring to Figure 20 The outer surface of the motor housing 4321 is a non-circular surface, and a protruding portion 4322 is formed by outwardly protruding the electric control portion corresponding to the protruding portion 4322. Based on the protruding portion 4322, as shown in Figure 20 、 Figure 20 A limiting groove 4112 corresponding to the protruding portion 4322 is provided on the first housing 411, and the inner side wall of the limiting groove 4112 is used to abut against the limiting portion 4311 in the rotating direction of the moisture absorption and removal member 42 to limit the rotation of the limiting portion 4311. That is, the limiting groove 4112 and its limiting wall are used to block the rotation of the motor housing 4321 with the rotating assembly, so that the motor housing 4321 remains fixed on the first housing 411. In one optional embodiment, the inner wall of the limiting groove 4112 is arranged on both sides of the protruding portion 4322 in the circumferential direction.

[0215] In one embodiment, referring to Figure 16As shown, the second driving member 43 further comprises a sealed housing 431, a motor housing 4321 of the second motor 432 is arranged in the sealed housing 431, and the sealed housing 431 is sealingly connected to the side surface of the first housing 411 away from the second housing 412. By additionally arranging the sealed housing 431, the second motor 432 is integrally protected and sealed in the sealed housing 431, which can further reduce the influence of water vapor in the main drying air duct 110 on the second driving member 43.

[0216] Specifically, as shown in Figure 22 the sealed housing 431 is provided with a plurality of second fixing ears 4312, and the second fixing ears 4312 are fixedly connected to the surface of the first housing 411 by fasteners (such as bolts, screws, etc.).

[0217] Optionally, as shown in Figure 18 the second driving member 43 further comprises a sealing washer 434, the sealing washer 434 is arranged between the sealed housing 431 and the side surface of the first housing 411 away from the second housing 412 and surrounds the output shaft 4323. The sealed housing 431 is fixed on the first housing 411 by fasteners (such as bolts, screws, etc.). The sealing washer 434 is compressed between the sealed housing 431 and the first housing 411, so as to maintain the sealing connection between the sealed housing 431 and the first housing 411, and further reduce the possibility of water vapor entering the sealed housing 431.

[0218] Correspondingly, as shown in Figure 19 the sealed housing 431 is outwardly convexly provided with a limiting portion 4311 corresponding to the protruding portion 4322, the protruding portion 4322 is located in the limiting portion 4311, and the limiting portion 4311 is located in the limiting groove 4112. The shape of the limiting groove 4112 is adapted to the shape of the limiting portion 4311, and the shape of the limiting portion 4311 is adapted to the shape of the protruding portion 4322.

[0219] As shown in Figure 18 and Figure 18 the side end surface of the first housing 411 away from the second housing 412 is axially recessed to form a motor mounting groove 4111 facing the second housing 412, and a part of the sealed housing 431 and the sealing washer 434 are arranged in the motor mounting groove 4111. The purpose of such arrangement is that, on the one hand, the shape of the motor mounting groove 4111 is adapted to the shape of the sealing washer 434 and the sealed housing 431, which is beneficial to the overall rapid positioning of the second driving member 43 during installation of the second driving member 43, and on the other hand, the output shaft 4323 can be as close as possible to the moisture absorbing and discharging member 42 in the axial direction, which is beneficial to reducing the deformation degree of the output shaft 4323, ensuring the transmission efficiency between the output shaft 4323 and the moisture absorbing and discharging member 42, and reducing the wear of the output shaft 4323 and the moisture absorbing and discharging member 42.

[0220] Next, please refer to Figure 18and Figure 18 As shown in FIG. 1, the moisture absorption and removal element 42 is introduced.

[0221] As shown in FIG. 1, the moisture absorption and removal element 42 includes a moisture absorption and removal medium layer 421, a first fixed support 422, and a shaft 427. The moisture absorption and removal medium layer 421 is fixed on the first fixed support 422, and the shaft 427 is fixed through the first fixed support 422 and the moisture absorption and removal medium layer 421. One end of the shaft 427 is also connected with an output shaft 4323 of the second driving element 43, so that the second driving element 43 can drive the moisture absorption and removal medium layer 421 to rotate. Figure 18 As shown in FIG. 1, the moisture absorption and removal element 42 includes a moisture absorption and removal medium layer 421, a first fixed support 422, and a shaft 427.
